        An LED grid, that could be used to show a multitude of things. Could be used as a website counter for example.
        It supports the A-Z, 0-9 and space characters. As you can see the colors are also user-definable. It also
        supports the context menu, and therefore the zoom. The first LED grid demonstrates this.
